EEG trigger display

Post by dana »

Hello.

I have a little problem with my imported .bdf files.
If I do my recording the display of my triggers in ActiView is just as I want it, however as soon as I import it into BESA I get for some of my triggers very different codes displayed.
Instead of a coded 201(which I see during the recording) I may get a 128 in the bdf BESA file. I am a little puzzled and wondered if somebody might know where that could come from? What I may not do correct. Sorry if that is a very obvious solution, but I am just a little out of thoughts.

I also contacted Besa support, since I am not sure where the problem might be coming from.

Best wishes
Dana

Hello again.

I just got a very helpful response from BESA.
It looks like I have not been sending my voltage level back to zero between my trials, which caused me all those double triggers in ActiView and misdisplays in BESA.
Sorry for this beginner mistake:)

Best wishes
Dana
